The Original Louis Joseph Vance: THE LONE WOLF:

The hero, Michael Lanyard (THE LONE WOLF), was a jackal reared in the brooding shadows through which slips the mysterious Seine. The story opens with Lanyard as a boy, a cub taught by pain and experience that the stroking of kindly hands was as naught compared with the fang of a single foe. And so this creature of the shadows, in the beginning driven by hunger, though in the end stimulated by pride in his art, prowled from the slums of Paris into the very halls of the mighty. At the zenith of his fame something settled upon THE LONE WOLF'S heart. The wild look of hatred went out of his eyes, the snarl bred of pain died in his throat. In this story Louis Joseph Vance discloses a new angle of his powers. It is the love story in the life of THE LONE WOLF that makes it human.
